How to do "If Clicked Else .."

I am trying to use jQuery to do something like

if(jQuery('#id').click) {
//do-some-stuff
} else {
//run function2
}

But I'm unsure how to do this using jQuery ? Any help would be greatly appreciated.

Edit: I'm trying to run a function if the #id has been clicked and specifically it is has not been clicked then run the function 2 ? i.e. I need to check firstly that the #id has been clicked before running
